Docker-compose receiving warnings once we upgraded from 1.16-1.18

After upgrading to 1.18 on my mac and a linux cli docker VM, we started receiving the below message.
WARNING: Connection pool is full, discarding connection:
The docker-compose command completes the up and down but we’re receiving a bunch of these warnings with the 1.18 upgrade. ex. below

docker-compose -H tcp://x.x.x.x:xxxx up -d --scale chrome=40 --scale firefox=40

Mac ver. docker-compose version 1.18.0, build 8dd22a9
Linux CLI ver. docker-compose version 1.18.0, build 8dd22a9

Anyone else seeing this or something similar? Thanks!
